## Description of change
Log a message if d3d9.dll (and friends) are found in the game root or
the modules directory.
This is to help with troubleshooting in cases where the user is unaware
that d3d9 is being used to inject other DLLs (e.g., ifs_layeredfs), or
when DX9 reimplementation is causing issues / crashes (e.g., dxvk).
## Testing
Observed the new messages being logged in both modules / root directory.

#304
## Description of change
Complain loudly about DLL conflicts. Show warnings for each DLL that
exists in both modules directory and the root.
This is not based on LoadLibrary hooks, just enumerating DLLs via
filesystem access.
Deliberately not using `log_fatal` since these are not necessarily going
to crash the game. Some people just love to have messy installs and if
the game booted fine before, it should continue to boot.
## Testing
Tested with/without `-modules`, with/without duplicate DLLs.
